Caleb will appear in the upcoming season of Pretty Little Liars and will travel to Ravenswood during the annual Halloween episode. The first episode of Ravenswood will premiere immediately after the Halloween special.

Blackburn, 26, has played Rosewood's resident bad boy since Season 1. First announced last month, Ravenswood comes from Pretty Little Liars executive producers I. Marlene King, Oliver Goldstick, Joseph Dougherty and Leslie Morgenstein, and follows five strangers who suddenly find themselves connected by a fatal curse.
